IMPROVEMENT IN GAs-BURNER'SM.

Specication forming part of Letters Patent No. 33,258, dated September10, 1861.

To all whom it may concern,.-

Be it known that I, CHARLES P. MILLER, of Philadelphia, State ofPennsylvania, havein- Vented a new and useful Improvement in Gas-Burners; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

My invention relates to a device, which I term a flame-spreader, forpreventing the escape of gas in an unconsumed state from the gasburnersin common use and for rendering the flame more steady, uniform, andbrilliant; and my invention consists of a plate arranged on the burnerin respect to the flame, as described hereinafter, for distributing thegas in a thin sheet, thereby allowing the oxygen of the air to have freeaccess to every particle of gas, the plate at the same time furnishingair in a heated state to the ame, and thus insuring a lmore perfectignition.

In order to enable others to make and use my invention, I will nowproceed to describe its construction and operation.

On reference to the accompanying drawings, which forma part of thisspecification, Figures l and 2 represent different"forms of myflarne-spreader as applied to differentlyconstructed burners; Fig. 3, avertical section on the line 1 2, Fig. l.

A represents what is generally known as a Scotch-tip burner, over `thetop of which is held by any suitable means the plate ZJ, the said platebeing in such a position that the gas escaping from the burner impingesupon it at a slight angle7 as seen in Fig. 3. In the present instancethe plate is connected to a split tube CZ of a proper size for embracingthe body of the burner. The plate, however, Inay be cast to and form apermanent part of the burner. When a fullhead of gas is turned on, itrushes from ordinary burners in a wavering irregular stream and with adisagreeable noise, in which case it is impossible to obtain a light ofa brilliancy proportionate to the amount of gas consumed, and when thegas is partially turned off, so as to escape from the burner in a steadystream, the light is oftentimes so insufficient as to require the use ofan additional burner. The wavering and flickering of the gas isoccasioned by its being forced out in such a body that portions of itare not ignited until they have combined withthe air, when a detonatingmixture isl formed, the explosion of which causes the noise andoccasions much of the unsteadiness of the light.

By using my improvement a much greater amount of light Inay be obtainedwith the same consumption of gas, and a much stron 0fer pressure bepermitted without more gas be# ing forced from the burner than can beimmediately consu med.

By distributing the gas in a thin sheet every particle of it has freeand immediate access to the air, which furnishes it with such a supplyof oxygen as Will insure a more perfect combustion than when the gasrushes out in a dense volume.

There is another advantage arising from Jthe use of my gasspreader. Theair as it is drawn to-Ward thev burner is brought in contact with theback of the plate b, and is consequently furnished to the iiame` in aheated state, Which causes a more perfect combustion of gas and thoroughignition of all its particles.

I do not desire to claim, broadly, a plate situated in contact with theflame of a gasburner or lamp; but

I claim as my invention and desire to secure b y Letters Patent- Theplate b, combined with a gas-burner and arranged on the same in respectto the llame, as set forth, so that the gas will in1- pinge against oneside of the said plate and be spread outward bythe latter in a thinsheet,I While the opposite side is exposed to the air, for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribiu g Witnesses.

CHARLES P. MILLER.
